To run Piwik you need at least PHP version $piwik_minimumPHPVersion

Unfortunately it seems your webserver is using PHP version $piwik_currentPHPVersion.

Please try to update your PHP version, Piwik is really worth it! Nowadays most web hosts support PHP $piwik_minimumPHPVersion.

Also see the FAQ: My Web host supports PHP4 by default. How can I enable PHP5?

Piwik is not compatible with the directive zend.ze1_compatibility_mode = On

It seems your php.ini file has

zend.ze1_compatibility_mode = On

It makes PHP5 behave like PHP4. If you want to use Piwik you need to set

zend.ze1_compatibility_mode = Off

in your php.ini configuration file, and restart your web server. You may have to ask your system administrator.
